Subject2.4.29, e100 and a WOL packet causes keventd going mad
Hi,

we have about 70 P4 uniprocessor machines (some with Hyperthreading
capable CPUs) running linux 2.4.29, which are woken up on the weekdays
by sending a WOL packet to them. The machines all have a E100 nic with
WOL enabled in the bios. The E100 driver is compiled into the kernel
and not loaded as a module.

If the machine which should be woken up is already running (because
someone switched it on by hand), the WOL packet causes keventd to go
mad and "use" 100% CPU:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
2 root 15 0 0 0 0 R 99.9 0.0 140:50.94 keventd

This can be reproduced on any of the 70 machines by simply sending a WOL
packet to it, when it's already running... No entry is made in the
kernel log.

The dmesg of an affected machine can be found at:
http://wwwcip.informatik.uni-erlangen.de/~simigern/cip-dmesg
Our kernel-config is at:
http://wwwcip.informatik.uni-erlangen.de/~simigern/cip-generic-config
lspci -vvv is at:
http://wwwcip.informatik.uni-erlangen.de/~simigern/cip-lspci

We are using a kernel.org linux 2.4.29 kernel patched with the current
autofs patch and ACL support.

Regards,
Michael
